Hi there!

I am trying to use this processor. I have found a very useful guide:

I am following the same steps but I am encontering this error:
"Copybook Path" validated against #{hdfs.output.raw-input-files}TGSS/copybook.cbl is invalid because The specified resource do not exist or could not be accessed: [#{hdfs.output.raw-input-files}TGSS/copybook.cbl]
Is anybody having this issue?
How can I solve it?

Thanks in advance



Of course I do have in HDFS in the route the copybook.cbl file.

While I am not familiar with this specific processor, maybe the following suggestions will help since the exception shared states that NiFi is unable to validate against the configured property value in the "CopybookPath" property :

1. The following string in your copybook path is a NiFi Parameter reference:


When NiFi enables this processor it resolves the above the value configured to it in the parameter context list.  If you replace above with the absolute local path instead of using a parameter, does it validate?

2. Also keep in mind that all components executing on the canvas are executed as the NiFi service user and not as the authenticated user who added those components to the canvas.  So make sure that the NiFi service user is able to navigate the resolved path to your copybook.cbl file and has proper OS permissions to read that file.

Thanks for the replay and my apologies in  my late response. The first sugestion does not work, the error is not related to it. In any case I tried both and get the same error.
The second sugestion, it is right we firstly had problems to reaching the route but at the moment it is solved.

Anyway I still couldnt solve my problem.


Hello Again Matt, 

I am going to give you more details about my problem.
I get this error: 




I am putting in the NiFi directory my copy. It is structured like that :



Then I have my cobol file. I have deleted all rows except 1 ( I have performed various test, full file, few raws ...) and I always ge the same error mentioned above.

This is the example of my cobol file with just one row:


Do you have any clue what is happening?


Thank you very much for your help
